McCutcheon index

From Wikipedia, the free encyclopedia
The McCutcheon index or chemotactic ratio is the ratio of the net displacement of a bacterium to the length of its actual path.[1][2]
\text{McCutcheon index}= {\text{Displacement}\over \text{Distance}}.

It is named after Morton McCutcheon who introduced it to describe chemotaxis in leukocytes.
